Abstract: Apparatus, methods, and computer-readable media for facilitating per bandwidth part TCI state or spatial relation are disclosed herein. For example, aspects disclosed herein provide techniques for enabling a UE (e.g., a reduced capability UE) to associate at least one of a TCI state or a spatial relation with respective hopping regions. An example method for wireless communication at a UE includes determining, while communicating using a first frequency range comprising a first set of frequency hops, at least one of a TCI state or a spatial relation for communicating using a second frequency range comprising a second set of frequency hops. The example method also includes communicating, after switching communication from the first frequency range to the second frequency range, using the second frequency range based on the determined at least one of the TCI state or the spatial relation.

Abstract: Methods, systems, and devices for wireless communication are described. A first network node may receive information via a first cell. The information may indicate a resource allocation for transmission of an initial uplink message via a second cell. The initial uplink message is a first uplink transmission scheduled to occur between the first network node and a second network node after a handover of the first network node from the first cell to the second cell. The first network node may receive a command via the first cell. The command may trigger the handover of the first network node from the first cell to the second cell. In response to the command message, the first network node may transmit the initial uplink message via the second cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, a first reported beam switch timing value and a second reported beam switch timing value. The UE may receive downlink control information (DCI) associated with an aperiodic channel state information reference signal (CSI-RS). The UE may receive the aperiodic CSI-RS based at least in part on applying a beam indicated in the DCI in accordance with one of the first reported beam switch timing value or the second reported beam switch timing value being based at least in part on one or more of whether tracking reference signal (TRS) information is configured for the UE or whether a repetition is associated with the aperiodic CSI-RS. Numerous other aspects are provided.

Abstract: The apparatus may be configured to configure a downlink BWP and an uplink BWP having at least one of a restricted uplink portion, a restricted downlink portion, or a guard band associated with one or more of the downlink BWP or the uplink BWP. The apparatus may also be configured to communicate with one or more UEs in the restricted downlink portion of the downlink BWP and the restricted uplink portion of the uplink BWP. The apparatus may be configured to transmit, to a first UE in a half-duplex mode of operation, an indication of a first set of resources for a full-duplex mode of operation of the base station and a second set of resources for the half-duplex mode of operation of the base station. The apparatus may also be configured to communicate with the first UE in the indicated first set of resources.

Abstract: Certain aspects of the present disclosure provide techniques for managing beam failure recovery operations. A method that may be performed by a user equipment (UE) generally includes determining at least one reference signal (RS) associated with a first cell that is configured without a control-resource set (CORESET). The method also includes monitoring the at least one RS associated with the first cell. The method further includes detecting a beam failure on the first cell based on the monitoring of the at least one RS.

Abstract: Apparatus, methods, and computer-readable media for facilitating phase jump estimation for SL DMRS bundling are disclosed herein. An example method includes receiving, from another device, first information at a first symbol of a first slot, the first slot including at least the first symbol and a first reference signal. The example method also includes receiving second information at a second symbol of a second slot, the second slot including at least the second symbol and a second reference signal, the first information and the second information being repetitions. The example method also includes generating a first reference signal copy based at least on the second reference signal and a phase jump between the first slot and the second slot. Additionally, the example method includes performing channel estimation across the first slot and the second slot based on an aggregation of the first reference signal and the first reference signal copy.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device such as a user equipment (UE) may determine to transition from a first duplexing mode to a second duplexing mode, where a first communication associated with the first duplexing mode at least partially overlaps in time with a second communication associated with the second duplexing mode. Based on the overlap, the UE may identify transition information for coordinating the transition between the first duplexing mode and the second duplexing mode. Using the transition information, the UE may transition from the first duplexing mode to the second duplexing mode, and may communicate with a second wireless device, such as a base station, using the second duplexing mode.
